rdlc 파일 인쇄 중에 예외가 발생했습니다

Question

내 rdlc 보고서에 문제가 있습니다. 인쇄를 시작하면 예외가 발생했습니다. 나는 그것의 유형이 무엇인지 모르지만 나는 스택 추적을 가지고있다. 보고서에

경로가 정확한지 확인하십시오.

다음

ThreadPool.QueueUserWorkItem(o => 
     { 
      var patientReportPresenter = PatientReportPresenter.Convert(patient); 
      using (var demo = new PrintComponent(patientReportPresenter, applicationSettings.PrinterName, "DataSet1", false)) 
      { 
       try 
       { 
        string exeFolder = Path.GetDirectoryName(Application.ExecutablePath); 
        string reportPath = Path.Combine(exeFolder, @"Template\Report1.rdlc"); 

        var report = new LocalReport 
        { 
         ReportPath = reportPath 
        }; 
        demo.Run(report); 
       } 
       catch (Exception ex) 
       { 
        string exeFolder = Path.GetDirectoryName(Application.ExecutablePath); 
        string reportPath = Path.Combine(exeFolder, @"Template\Report1.rdlc"); 

        MessageBox.Show(
         ex.Message + Environment.NewLine + ex.StackTrace + Environment.NewLine + reportPath, 
         @"Print error", MessageBoxButtons.OK, 
         MessageBoxIcon.Error); 
        return; 
       } 
      } 
     }, null); 

내 인쇄 클래스는 다음과 같습니다 :

public class PrintComponent : IDisposable 
{ 
    private readonly string _printerName; 
    private int m_currentPageIndex; 
    private IList<Stream> m_streams; 
    private readonly string _dataSetName; 
    private bool _landscape; 
    private PatientReportPresenter _patientReportPresenter; 

    public PrintComponent(PatientReportPresenter patientReportPresenter, string printerName, string dataSetName, bool landscape) 
    { 
     _patientReportPresenter = patientReportPresenter; 
     _printerName = printerName; 
     _dataSetName = dataSetName; 
     _landscape = landscape; 
    } 

    private DataTable LoadSalesData() 
    { 
     var table = new DataTable(); 


     table.Columns.Add("Address", typeof(string)); 
     //... 

     table.Rows.Add(_patientReportPresenter.Address, ...); 

     return table; 
    } 

    private Stream CreateStream(string name, 
           string fileNameExtension, Encoding encoding, 
           string mimeType, bool willSeek) 
    { 
     Stream stream = new MemoryStream(); 
     m_streams.Add(stream); 
     return stream; 
    } 

    private void Export(LocalReport report) 
    { 
     string deviceInfo; 

     if (_landscape) 
     { 
      deviceInfo = 
       @"<DeviceInfo> 
      <OutputFormat>EMF</OutputFormat>

     } 
     else 
     { 
      deviceInfo = 
      @"<DeviceInfo> 
          <OutputFormat>EMF</OutputFormat> 
          <PageWidth>8.3in</PageWidth>

         </DeviceInfo>"; 
     } 
     m_streams = new List<Stream>(); 

     Warning[] warnings; 
     report.Render("Image", deviceInfo, CreateStream, out warnings); 

     foreach (Stream stream in m_streams) 
      stream.Position = 0; 
    } 

    private void PrintPage(object sender, PrintPageEventArgs ev) 
    { 
     var pageImage = new 
      Metafile(m_streams[m_currentPageIndex]); 

     var adjustedRect = new Rectangle(
      ev.PageBounds.Left - (int)ev.PageSettings.HardMarginX, 
      ev.PageBounds.Top - (int)ev.PageSettings.HardMarginY, 
      ev.PageBounds.Width, 
      ev.PageBounds.Height); 

     ev.Graphics.FillRectangle(Brushes.White, adjustedRect); 
     ev.Graphics.DrawImage(pageImage, adjustedRect); 
    } 

    private void Print() 
    { 
     if (m_streams == null || m_streams.Count == 0) 
      throw new Exception("Error: no stream to print."); 
     var printDoc = new PrintDocument {PrinterSettings = {PrinterName = _printerName}}; 
     if (_landscape) 
     { 
      printDoc.DefaultPageSettings.Landscape = true; 
     } 
     printDoc.DefaultPageSettings.Margins = new Margins(0, 0, 0, 0); 
     if (!printDoc.PrinterSettings.IsValid) 
     { 
      throw new Exception("Error: cannot find the default printer."); 
     } 

     printDoc.PrintPage += PrintPage; 
     m_currentPageIndex = 0; 
     printDoc.Print(); 
    } 

    public void Run(LocalReport report) 
    { 
     report.DataSources.Add(new ReportDataSource(_dataSetName, LoadSalesData())); 
     Export(report); 
     Print(); 
    } 

    public void Dispose() 
    { 
     if (m_streams != null) 
     { 
      foreach (Stream stream in m_streams) 
       stream.Close(); 
      m_streams = null; 
     } 
    } 
} 

내가 잘못 어떻게해야합니까 여기
